Hemangioblast

Hemangioblast is a type of cell that forms during the development of the blood vessels and blood cells in an embryo. These cells are precursors to both endothelial cells, which line the interior surface of blood vessels, and blood cells. Hemangioblasts are found in the mesoderm, one of the three primary germ layers in the very early embryo.

Development

Hemangioblasts are formed during the process of vasculogenesis, the formation of the circulatory system. They are the earliest cells that can be identified as precursors to the blood and vascular system. Hemangioblasts differentiate into angioblasts, which are the precursors to endothelial cells, and hematopoietic stem cells, which can develop into all types of blood cells.

Function

The primary function of hemangioblasts is to give rise to the cells that make up the blood and vascular system. They are critical for the formation of the circulatory system during embryonic development. Hemangioblasts also play a role in the repair and regeneration of the blood and vascular system in adults.

Clinical significance

Hemangioblasts have been studied for their potential use in regenerative medicine. Because they can differentiate into both blood and vascular cells, they could potentially be used to treat diseases of the blood and circulatory system. However, more research is needed to understand how to control the differentiation of hemangioblasts and to ensure their safe use in patients.
